My guess is it died and he wasn't willing to spend the money fixing it. If that is the case, it is not something you can just ask how to make it work (the power on sequence you mentioned should work if everything in the control is OK) without troubleshooting what is wrong with it.
I have seen the power supplies fail a couple times, and based on your description, seems like a likely scenario so you can start by verifying if the power supply has proper incoming and outgoing voltages.
